By using the appliance management interface, change its IP address. Open the management interface using the new IP address, update the traffic control settings with the new IP address and re-register with the vCenter Server Lookup service. By returning to the appliance management interface, repair the Replicator Service. Finally, repair from the remote site by using the updated Public Service Endpoint address.

Note: Applying any network changes leads to temporary network outages. For example, the browser connectivity to the management interface is interrupted when being accessed through the network adapter that is being reconfigured.
Perform the exact steps for each appliance role. This procedure applies to the following appliance roles:
  • On-premises appliances roles:
    • On-Premises to Cloud Director Replication Appliance - perform steps 1-5 only.
    • On-Premises to Cloud vCenter Replication Appliance - perform steps 1-3, then perform steps 5-13.
  • Provider appliances:
    • vCenter Replication Management Appliance - perform steps 1-3, then perform steps 5-15.
    • Replicator Appliance - perform steps 1-4, then perform steps 12 and 13 only.

For information about configuring the appliance IP address in a cloud site backed by VMware Cloud Director, see Network settings configuration.

Prerequisites

Verify that VMware Cloud Director Availability 4.4 or later is deployed in the vCenter Server site.

Procedure

    2. Select Appliance login or SSO login and enter the root or the single sign-on user credentials.
    3. Click Login.
  2. Change the network adapter IP address of the appliance.
    1. In the left pane, click Settings.
    2. Under Appliance settings, expand the Network section.
      You can see all the network adapters that are added to the appliance.
    3. To change the IP address, next to a network adapter name, for example ens160, click Edit.
    4. In the Settings window for the selected network adapter, configure its network settings and click Apply.
      Option Description
      IP Mode Select either:
      • IPv4
      • IPv6
      • Unconfigured turns off this network adapter and deletes all of its settings, including static routes. Use this cleanup procedure, in case there are configuration leftovers that are causing unexpected network behavior.
      Type:DHCP
      Note: After selecting DHCP to provide the network configuration, all manually configured network settings, such as DNS servers, search domains, static routes, and MTU size are removed. To manually add, next to Network, click Edit then enter:
      • DNS servers
      • Domain Search Path
      Type: Static Enter the static configuration.
      1. In the Address/Prefix text box, enter a CIDR address - IP address, followed by a forward slash and a network mask or a prefix length. For example, enter 10.20.30.41/21.
      2. In the Gateway text box, enter a gateway that is in the same network as the provided IP address. For each IP mode, you can use only one default gateway. If you are configuring a second adapter in the same IP mode, you must not enter a default gateway.
